Large bottle-shaped container having substantially rectangular cross section

Abstract

A large container made of synthetic resin, and comprising a neck and a body; the body having a substantially rectangular cross section, and including an upper body and a lower body; the upper body containing a center of gravity of the container when filled with liquid; the upper body having a waist section containing the center of gravity; the waist section having a grip, the grip being not adapted to absorb a negative pressure in the container; and at least one surface of the lower body including a vacuum panel.

Field of the Invention[0003]This invention relates to a large bottle-shaped container having a substantially rectangular cross section. More particularly, the present invention relates to a bottle-shaped container that does not need to absorb a reduced internal pressure in the container by a grip thereof, and that has an improved rigidity for the entire container.[0004]2.

AI Technical Summary

Benefits of technology

The present invention provides a large bottle-shaped container with improved properties for absorbing reduced internal pressure and increased rigidity as a whole. The container has a neck and body with a substantially rectangular cross section, including an upper body and lower body. The lower body has a vacuum panel that absorbs all the negative pressure generated in the container, while the grip is not affected. The container also has a vacuum panel with a large area and a transversal rib to prevent permanent deformation. The technical effects of the invention include improved resilience and reduced permanent deformation of the container.

Problems solved by technology

Meanwhile, it is sometimes impossible for a large bottles to absorb a reduced internal pressure in the bottle only by means of vacuum panels of the bottom portion.

Then, there arises a risk that the grip is permanently deformed and that an appearance of the bottle is damaged as a result of permanent deformation.

Still additionally, since the vacuum panels inevitably show a large total surface area (particularly when a further vacuum panel is formed in the top portion in addition to the vacuum panel formed in the grip), such a large total surface area of the vacuum panels by turn restricts a design freedom of the bottle.
